The Shield of Absorption is a magic item owned by Liecen Varonos.
In the series Edit
The shield was first shown to Silaqui by Wes Pommiliòne, its creator, when she came to ask about the progress on the gem she had asked Wes to appraise. He requested that she give it to a melée fighter in her party, and after signing a release form of some kind, she gave it to Liecen.
