OK I chanced 100 sacrifices to the ritual Contact Old Ones. I was hoping for a sizable army. Instead I got a single Basalt Queen. But she is like an army.

And her rituals DO allow her to call an army. And her spells allow her to call water elementals in battle. PLUS she is a giant. She can move much faster than I can. So I think I will allow her to continue the exploration. And I will try to have sacrifices available for her to summon Army of the Deep when she finds something interesting.
The Troll Mum is sniffing around my new Citadel. Im tempted to let her have it. It will give them a reason to expand here. Besides, I can still hold to my plan. I can hide in the citadel of my ally then jump into the water when danger comes.
