Mathis will show everyone his defensive plan. It requires us to split into equal sized groups, with a spotter and a fight on each floor. The stairs have tables with large stacks of books on them that can be used to throw or push down the stairs. Once the entry point is determined we will all work our way to them. Our greatest ally will be surprise, followed by stealth, and then all out ferocity.
These "People" are coming here to destroy this library and kill anyone standing in their way. Remember that. Take them out with extreme prejudice, as they will kill you or kidnap and experiment on you if you don't. If we can take out enough of them to gain the upper hand in numbers, then we can capture the last one and maybe get some answers.
