In your opinion would a Warforged be immune to an Illithid Tadpoles effects, and the Body Thief effect of an Intellect Devourer? Basically do they have an actual “brain”? Mechanically, warforged have no special immunities to these effects. I assume that the warforged have something in a cranial cavity that functions as a brain and can be affected by these things, even though it's not physically similar to a HUMAN brain.

It may not be a satisfying meal for a mind flayer, but they CAN still eat it.

Out of curiosity then, in Wayfinders Guide it mentions a headless Warforged (pictured), is this a very rare outlier or would this effect the previously questioned things.
Or somehow could it end up with 2 creatures inhabiting one body? (Also thank you for the reply 🥰) It’s a rare outlier. Mechanically, 5E warforged are humanoids; if a resistance or immunity isn’t explicitly called out, they’re treated like other humanoids.

believe i read this somewhere last night but can’t find it – in addition to specifying the conditions for an overlord’s release, would the draconic prophecy specify the conditions for their being rebound once (partially or wholly) released? Absolutely. The Prophecy is a map to possible futures; you just have to find the path leading to the future you want.

what kind of shops or vendors can players encounter in faraway places, such as deep Xen’drik, The Frostfell, Argonnessen etc? What kind of currency would they use? Interesting question. This is something I'd want to address in a short article on my website rather than a tweet. I'm taking questions for those articles from my Patreon supporters… but I know you ARE a Patreon supporter, so I'll add it to that list!

There's been some great answers so far that I won't repeat (aside from: hire @laura_hirsb). For some others… consider the Race of Eight Winds. as background color. Let's see some team spirit! Do you think the Gargoyle has a shot this year? https://t.co/LqVuRdxTf7 #Eberron

I always like to highlight monsters working in everyday roles: the harpy courier, the ogre working on the construction city. And it never hurts to introduce a giant owl. My last campaign was set in Callestan, and the first thing I did was to work with the players to pick their personal dive bar. Where do they hang out between adventures? I also made sure at least one of them had ties to local gangs (Boromar and secondhand Tarkanan).

— Keith Baker (@HellcowKeith) April 29, 2020

House Tarkanan is complicated. They’re more Magneto than Xavier, but they’re a persecuted minority seeking to gather and protect others of their kind. They break the laws of the land — but in their eyes these are the laws of oppressors who killed their ancestors.

— Keith Baker (@HellcowKeith) April 2, 2020

House Tarkanan believes that they’re acting in the best interests of their own people and they are willing to harm their oppressors to do it. In THEIR view that’s not evil. In the view of the majority they prey upon, it is.

Are there any groups who use Cards to cast spells?

I have a player who is really set on making a Tarot Card Sorcerer and they are very open to know of any canonical eberron groups that already fit that broad description before i make one up. There's no defined cartomancy forces in canon Eberron that I'm aware of, though it's possilbe I'm forgetting something.

— Keith Baker (@HellcowKeith) July 15, 2020

Even if noncannon, If I had to homebrew a sect of cartomancers. Perhaps one of the following:
-Draconic Prophecy observers (either chamber or Dusts followers)
-Practitioners in Aundair
-Tareza Underlings

Any others good candidate?

and thanks for your time and input of cannon! All three of those ideas make sense to me! I could also see it as a side path of sigilry (the arcane science used to create scrolls) and thus perhaps popular with House Sivis or Zilargo.

what does Droam’s Navy Look Like? Giants on huge Boats?
If no official answer I have no problem making one up but wanted your input. I don't think that Droaam has much of a navy. They surely have shore defenses on Vralkek, but they're a young nation with limited use for sea power. In terms of armament, the main thing I'd see would be a contingent of harpies. Who needs catapults when your enemies abandon ship?

Do Dragonmarked Houses tend to act like modern corporations in legal issues? IE, if you tried to sue them, they’d be inclined to settle rather than, say, hire assassins to silence you? It depends entirely on who you are and the circumstances of the case. We have suggested that the houses would, for example, sabotage an artificer doing work that threatens their monopoly.

— Keith Baker (@HellcowKeith) April 19, 2020

If you’re a beloved public figure or have powerful friends, then sure, I’d expect them to settle. If you’re a nobody? Or a sketchy adventurer who regularly engages in dangerous tomb robbing? They might certainly arrange an “accident.” Even if you DO take the case to court, where is it happening? Do you trust that they can't buy the judge or otherwise game the system?

— Keith Baker (@HellcowKeith) April 19, 2020

I’d say that overall, the general tone of the houses is more dystopian “In the wake of the Last War, do they have too much power? Can anyone control them?” than “The legal system keeps them entirely in check! Yay!” The idea of it was my character, a mid-level adventurer who's on staff at a newspaper, was put in danger by Cannith negligence on an assignment he was doing for them. Was wondering if they'd be more inclined to settle or send assassins after him to avoid the bad PR.

— Maximilian Ximenez (@maxximenez) April 19, 2020

My point is that _assassination_ may be an extreme answer. But consider things modern corporations DO do, like, say, buying your newspaper and having you fired. Slander, blackmail, and threats could all be on the table—all through third parties, of course.

— Keith Baker (@HellcowKeith) April 19, 2020

They might not even need to buy the newspaper. It could well be that one of the local upper management in Cannith is drinking buddies with the owner of your newspaper and will now owe them one Good point!

Or possibly as likely if not more so our members of the same social club. Maybe they both wear similar sets of silver rings on each of their fingers Funny you should suggest that – I was thinking the EXACT same thing!

— Keith Baker (@HellcowKeith) April 19, 2020

There's one more important issue, which is whether the Code of Galifar considers corporate negligence a crime. Given that there's clearly no antitrust laws (as the houses are government-sanctioned monopolies) it's quite likely that laws are generally house-friendly.
