Now, now. Lets not overwhelm the new guy.
I see some kind soul seems to have intervened and provided linkage for the article.
The Aeon may be full, but there should be a spot for this guy in the Eucharis if you can survive the hectic posting rate.
The story seems to have been changed somewhat since the mods last looked at it, so I'll just comment on what I've read.
For starters, smoking is apparently a severe criminal offense in Yamatai, most of the ones that do do it are usually Nepleslian immigrants with a dark, unwatched corner and a smoke extractor.
Traditional tattoos for hemosynth based species like Yamataians are impossible, however you were smart to mention the burning with a blowtorch thing. Another possible way for him to get that effect would be with volumetric projection on the skin, however I'm not entirely certain if Yamataian's can do that.
With your character being thirty years old, but the Yamataian body only created four or five years ago he would probably be a Geshrin before he swapped to a new body. Just an added bit of backstory if you want it.
Oh yeah, and crime is also apparently rare in Yamatai. Most of your characters mercenary work would most likely have been either in Nepleslia or out in the far colonies. The SAoY doesn't like any organized force with guns on their turf but them, so mercs are either extremely careful/low profile or dead while in YSE.
Well, that's about all from me. Be sure to come on IRC sometime if you have any questions or just want to chat. Don't worry, we don't bite.
