It's probably worth noting that FFXIV is significantly different from other titles in the franchise, in that many of its key characters are in their 20s and above. Most of the Scions, notably, are in their mid- to late-20s, if not in their 30s. For that reason, I've been quite comfortable imagining my character to be in his 20s as well. Lyland, in my mind, arrived in Eorzea in the autumn of his 20th year, and is now 23.

The trope in anime and JRPG is that of characters being considered over-the-hill by the time they're 20. Heck, they're ancient by the time they're 29, and are, for most intents and purposes, already in retirement by that age. I'm glad that FFXIV is generally bucking the trend.
