So I (like I'm sure all of you) noticed that the warp gem item has a number and when you warp somewhere it asks you to select the location from a drop down menu of warpers you activated. This leads me to the conclusion that there are multiple warp gems that are obtainable.
Since you only get one from the warp ring quest I was wondering if anyone has found any others? I heard rumors there is one in the king's chest, so if anyone has accessed that yet, can you confirm? If that's not the case I'd encourage everyone to be on the look out for small additions around the map or anything that feels off? My other theory is it is VERY rarely acquired from treasure chests or looting?
This is all speculation tho.
