With 0 ranks in Lore: History and only 2 int? Prrrobably not. You would only know the stories that everyone else knows, which aren't usually fit for such an event.
Well that's unfortunate...
Ok, slightly different plan then.
[X] Now, Hiruma-san. You should not be so hasty in your censure.
[X] The Crab Clan sacrifice so much in their service for the Empire, and so there are many others that are fortunate enough that they need not do the same. The stories of those who do must always be told though and so we are most fortunate for those like Ikoma-dono who tell their tales.
--[X] A shame then that then that the story he has chosen suffers so for the length of its telling. There are many others that shal now go untold.
--[X] Indeed this is an odd story for Ikoma-dono to choose - for while we must always remember and respect the ancestors who came before us, they who worked with a singular purpose as only some still do - there are so many Samurai, so nearby who sacrifice so much for the safety of the Empire this very day upon the Wall. Is that not a more appropriate story of Valor and Sacrifice?
---[X] Perhaps another day I shall tell that story. Unfortunately I have little time left now, and obligations that take me elsewhere.
[X] Spend the next day or so speaking to Crab warriors about their own stories of valor and sacrifice, looking for a good one. Talk with Hiruma-san to see if he can recommend an appropriate story.
-[X] Once you have a proper story gathered together, present it for the crowd in an appropriate venue.
--[X] A story of those who serve upon the Wall; of their courage, of their valour, their sense of duty and above all their sacrifice. (Make those listening think more favourably of those who serve on the Wall and the Crab as a whole.)
[X] By attempting to assist - A few people may be offended by your criticisms of their skills, but a bit of assistance in helping them develop their skills could be well-received.
[X] Spy on them - Wakaba has gotten much more skilled at intrigues of late, and due to the disorganized nature of such factions, they would necessarily be easier to observe than their host clans.
