ToME: the Tales of Maj'Eyal

I know this is a really stupid question, but I was playing earlier and I had a apopup saying DarkGod gifted me the DLCs for Tome4. I am a new player, only been playing for a couple weeks. How do I access this content? Thank you in advance.

Alas these are not the DLC being gifted - It's the DLC's anniversary event, and you get a little commemorative item into your **character's** inventory in-game.
