Building precarious colonies

These three set out to help a colony build structures. Said colony has set up in rather difficult to get to location, part of the way down a cliff. While it might be a  defensive location, it's certainly hard to get to. These colonists have volunteered to be part of the grappling assembly line- Hivoo loading up Isaac with materials, Isaac repelling down the cliff to give the materials to the colony, and Milli in charge of keeping the line attached to Issac safe/pulling him up when needed.
