Shingen is an excellent person to contact for this, as he can reach out to the Story Team members on here, and contact them.
Do you happen to have anything official proving this storyline prize? Anything from the website for the original event, or something similar? While the Story Team have been pretty open in accepting and trying to give updated story prizes in the fiction, having something to prove it might be necessary.
I found this information in the "The Jade Hand" web, where are saved results of past koteis.
In addition, there are an official fiction linked there, to the official web of L5R.
I have comented that to Ukyo but I'll do the same with Shingen.http://www.l5r.com/2009/05/23/the-war-o ... e-part-11/
In the last part, there is a Hare talking to a Scorpion Imperial Chamcellor.
Will be enought proof?
May the Shourido be with you.
