Can I understand it as:There is only one Weave in the multiverse,and wizards of the Toril named the only Weave Mystra?Or it is:The different worlds have different Weavemasters,and they rule the Weave of their own worlds?

I’d put it another way:
Toril and all other worlds have multiple ways of accessing the energies of each world. And usually call the non-mechanical, non-engineering ways of accessing those energies “magic.”
ONE of the ways on Toril is arcane magic (in D&D, wizard 2)
…and sorcerer spells), and those who have the Gift (ability to wield arcane magic, which they call the Art) or study arcane magic (sages) refer to their way of accessing the energies as "the Weave." The Weave IS Mystra, the goddess of magic, and the Weave only…#Realmslore— Ed Greenwood (@TheEdVerse) March 9, 2020

…extends throughout Realmspace (Toril and moons and the void/heavens around them). Other worlds have other ways of accessing energies, and may have their own equivalents of the Weave (not identical, and not governed by Mystra) or may not. Abeir likely has an.. 4)
…equivalent, because it's the sister world of Toril, so similar and even sometimes (the Sunderings) contiguous with Toril, so that elements of the two worlds get swapped, but Weave-based spells don't work on Abeir; but innate spellcasting abilities do. I.e. the..#Realmslore— Ed Greenwood (@TheEdVerse) March 9, 2020

…world energies are similar enough that magical effects can be near-duplicated, but not how they’re brought about.
So in theory, a powerful archwizard from Toril would have to start all over learning how to work magic on Abeir, and if no developed system o 6)
…working arcane magic, they may never hit upon how to create magical effects on Abeir, or may spend the rest of their lives experimenting and making very little headway.
In theory, all worlds MIGHT have their own Weaves (under various names) and their own gods…#Realmslore— Ed Greenwood (@TheEdVerse) March 9, 2020
Whoops, a word is missing from #6 in my reply:
"working arcane magic EXISTS, they"

…of magic, or not. “Weavemasters” is a term I coined back in the 1990s for anyone who’d mastered the Weave (understanding its workings enough to not need the trappings of arcane magic like material, somatic, and verbal components), so they could work magic by.. 8)
…silent act of will, rather than conventional casting. Accomplished, experienced Weavemasters (like most of the Chosen of Mystra) can think of what they want to do, then mentally call on the Weave to do it. So they can work magic when tied up, gagged, and so…#Realmslore— Ed Greenwood (@TheEdVerse) March 9, 2020

…on, when traditional casters would be rendered helpless. They control the Weave only so much as they call upon it, and so are not the same as a deity of magic who is the Weave (e.g. Mystra) or who governs the Weave.
So Mystra IS the Weave within Realmspace 10)
…only, and is greater than a Weavemaster. Other worlds have other systems of magic, and even Toril has other systems of magic (divine magic, for example). Most other systems of magic use the Weave for convenience, but need not do so (travel from real-world…#Realmslore— Ed Greenwood (@TheEdVerse) March 9, 2020
