4. IreTome

Ireland + tomes knowledge? This would fit Old Sharlayan. Ire is also a word to describe fear.

"Ire" means anger, not fear.

Also I'm not sure why you would be wanting to use the name of a real-world country in the title of a fantasy game. There's not even any relevance between it and Sharlayan, other than being loosely in a similar location on the borrowed-from-real-world continent layout. (Though if anything, I'd guess it might be geographically more equivalent to Iceland? Further off from mainland 'Europe', and possibly on a continental plate boundary, as Iceland is, from the look of the island chain.)
