About
Guicool is a mod author from Brazil, who created several Skyrim follower mods on the Steam Workshop from 2012 to 2015. In November 2016, he released a fully voiced custom companion mod for Fallout 4 called "Ellen, the Cartographer". The mod is about the titular character being a part of the game, functioning as a vanilla follower, with her own questline. She's voiced by user potasticpanda (who made the custom voiced follower mod Recorder for Skyrim).
