So I was wondering what the story is for Laika and her brother and if they have any impact as of right now? They have images so I imagine they are fairly important to some degree, though I have no clue what to do with them.

Laika and her brother will be among the first Issids the MC can add to his household in the 0.8.1-0.8.2 updates. Issid is a Raanic name for non-slave servant - even if most Issids rarely live a better life than a slave. What is an abandoned cultist temple full of zombies compared to a sprawling household and daily dinners at The Golden Dragon? :)
