There were two avatars in Realm earlier (EU West, did not make a note of which Realm). I positioned myself between them for the screenshot. One is above me, one below, on the minimap. The odd thing is only one is working, the lower one (with all the people). The top one was invulnerable on about 40% health. Presumably it just stopped on a transition from one phase to another.
The bottom one was working normally, and as soon as it was defeated the top one started working again. I arrived when they were both there, so I am not sure what happened to get them in that state. I think the top one appeared first, then the bottom one just before I arrived.
