At first, I thought this was a thread about lalafells as sexual predators (not too farfetched, based on their conversations).

Then after reading the OP, I wondered how many Rocs actually fly into underground tunnel networks. Then I was thinking about where I've seen Rocs; the FATE "Roc of Ages" is in Coerthas, closest to Ishgard, I'd guess. Then I wondered how many lalafells originated in Coerthas.

Then I remembered a quote from an Austin Powers movie reminding me not to think too much about the details.......
