I'm running a 5th Edition D&D campaign and one of the players asked to be an Asura from Guild Wars 2. By talking it through with the player, we decided to use the Tinker Gnome racial characteristics, with a couple of small tweaks. So far, so good.
At some point in the campaign, the Asura will be returning to its home plane. I'm not a Guild Wars 2 player, so I need to collect some information regarding Guild Wars 2. However, I'm looking for setting information specific to RPGs (monsters, cities, etc.), rather than any game guidance or tips.
Would a question about where to find this information be on topic?
