Trials of the Realm Bios
"One of the key strongholds during the Goblin Scourge, Glacier Keep stands to this day on the borders of the Frozen North. It originally belonged to a different noble family, but House Aico still keeps it manned in respect of the long departed."
Ruby Throne (Beach Bash Update)
"House Aico controls the Ruby Throne and stands as one of the most influential noble houses of the Realm. Sitting on the Throne is the head of the house, Lian. The Throne is flanked by Lian's closest advisors: the Primus of the House and her trusted knowledge-seeker."
- Moonlike symbols have appeared in all maps that appear to be part of this area, with symbols appearing near the spawn rooms on both sides of Ice Mines, atop various doors and structures in Snowfall Junction, and a possible portrayal of an eclipse on the old version of Frozen Guard. It is unknown what, if any, connection these maps have to the Followers of Io.
- As implied here, House Aico doesn't seem to be the only royal house present in the tundra.
