Elysium Loyce is a nice place without that blizzard, and with Aava dead I could waltz up to the main cathedral and hop down into a pit called "the old chaos" - where the king of this place (the "ivory" king) led his knights into a losing battle. Well, I was surprised that one ivory loyce knight ally came with me but the number of swarming and respawning evil ebony loyce knights (good to be color coordinated) was simply too much to handle.
The solution to being outnumbered...
It was clear I'd need to find more backup so I decided to explore the city, block by block. In addition to the ice skelies, those snow beggars who I previously ignored now doubled as assassins but they were nothing compared to the dreaded ice bandicoots who have the same rolling attack as those skeleton wheel guys. I also have to contend with invaders Hexer Nicholai (who enjoys "slow" spells) and Witch Donna (who can't aim even if her life depended on it). There's also a covetous demon, shiva knights, and evil golems - clearly I'm running past a lot of stuff! :P
...is to bring more allies! :P
Eventually I do find and free three more of the ivory knights, and then recruit players Django and Sunlight Brother "Sunbro Forever" to assist in the battle of the old chaos. It's an epic fight. Django falls early, and is soon followed by the white knights as the black knights finally run out. The Ivory King makes an appearance and proves to be a dangerous foe, but by taking turns to tank him Sunbro Forever and I are victorious, with Sunbro landing the finishing blow. With that, a second crown is now in my inventory. Thank you Django and Sunbro Forever!
