Magnus’s RPG empire on the portal.

I cast Summoning of the Heavens on the succubus!

Several succubi are destroyed. But meanwhile, the Archdevils summon Cave Lords. I cast Ice Golem on the Archdevils, again, again, again, one Archdevil disappears. Suddenly, a portal appears, and demons start pouring out. I try to banish them, but the pressure is too great. I concentrate and close the portal, but I lose 25 health. Joe, I think you need to sneak into the city and help defend the city's altar.
