The realmwalker event in nahantu is bugged. I see the hatred rising symbol, but not the realmwalker simbol. I cannot attach print screen, cause the forum won’t let me post links.
The realmwalker is there when the hatred rising icon appears. It’s usually at 30 minutes past the hour. The event spawns after 5 minutes. Go to the region when the icon appears and look for the gray skull with horns - it will show on your map and minimap. I would post screenshots but you can’t post them here. This is most definitely a bug.
