Tell them to find another game?

How do you think is the best way to deal with a player who just won’t listen when you are dming? In all seriousness, if a player isn’t respecting the work you are putting into running your game, then talk to them about it. If they continue to be a problem, maybe this isn’t the table for them.

I’m sure this has been asked before, so I’m sorry in advance. The bridge at Thaliost is ruined, which leaves only the routes through Cyre. Can the lightning rail be taken through Cyre? I have all the previous edition books, but I can’t find the reference. No lightning rail through the Mournland, though someone trying to establish one sounds like a great adventure plot!

Airships and coastal travel are options.

@JeremyECrawford while atop a controlled mount, can you grapple a creature and drag it around with the mount's movement? Or would the mount's movement end the grapple?

The rules detail how to move a creature you're grappling by using your own movement. If you try to move the creature some other way, you need to use the rules on lifting and carrying.

As DM, I'd allow your mount to move at half speed so that you could maintain a grapple. #DnD https://t.co/ndbZ8WHi4U

How does different times / calanders affect certain things? For example, if the world has a day that’s 20 or 25 hours long, do things with a duration of 1 day last the 20/25 hours, or the usual 24? Things that last or take 1 year, if the year is 200 days or (1/2)400 days, does it take / require 200/400 days or is it the 'usual' 365? Same for on a different planet, or in space. Would a leap year take the extra day? (Would be helpful to know when making multiple / different worlds and spelljammer settings) (2/2)
