Wasn't your guy a dark wizard? Ministry loyal and opposing the Order or just a dark magic practitioner with order loyalty? Asking since it would effect your guy if he was a ministry loyalist and if he wasn't. The bio made it seem like a dark magic practitioner with disagreeable views to the ministry, so perhaps more inclined to help the Order but then again I could be wrong. Just seemed that way from what I saw.
If you have a good reason though and way of being at the cave or knowing others are there, then i would assume it's all good.
Dark magic practitioner with Order loyalty. He hasn't gotten involved at all, but from what he's heard he definitely believes the Ministry's corrupt and everything.
I was thinking that Ira would be living in the woods, kind of close to the cave, see the lights in it or something. If that's too coincidental then after the next timeskip the group runs into his place or something like that. Whatever's most convenient.
