There was a limit to how much Martin could care for the well being of others, and he had reached it.
Hearing the wail of a soul wounded so deeply. To him this was akin to discovering a new element, reaching new heights, becoming of a deeper understanding.
The human mind was a complex puzzle and martin just found the last twisted little piece.
Martin's mind went in overdrive, working to comprehend impossible calculations derived from scarring emotions.
Frantically rewriting every thought in every mind connected. To a point where he forgot to keep his blood puppet under control and it collapsed into catatonic state.
He forgot his guidance to Rhyss, this may or may not have been the cause of the illusory wings, he noted in his calculations.
For a second he forgot everything... then it returned. All of it. A faint psionic glamer of laughter, heard in the back of one's mind was shared by hundreds.
