So, on our Frost Giant quest. Kelvin says that the Frost Giants are from Grizzleheim. Right? So why don't we summon Ymir in the Grizzleheim? It dosn't take to go there and you could summon in Northguard. ALso grizzlehim haddn't come out yet when they made the Lv. 48 spells. So we knew about grizzleheim first.

This means that KI was hinting to the POSSIBLE (at the time) world of Grizzleheim before it went live. Like when they give multiple hints about Celestia that has been confirmed.
