Anna "Grim" Grimsdóttír is the Technical Operations Manager at Third Echelon.
Not to much is known about Anna other than what is learned through her communications with Sam Fisher. She had once mentioned to Fisher that while he was fighting overseas in 1989, she was in the tenth grade which for some reason disgusted Fisher. One thing that Anna is known for on a couple different occasions is that she likes to make fun of Sam Fisher for being an "old" man. Fisher gave her the nickname "Grim", which was later transformed to Grim Reaper by Leon Coltrane. Grimsdóttír is a second-generation American; her mother came to the U.S. alone from Akureyri, in Northern Iceland.
