Runes of Magic US / AU

Since you're lvl 63, you have access to up to lvl 65 quests. Make sure you've done all of the required quests in the Magical Reconstruction line: http://www.runesdatabase.com/quest/list/1.220#quests:+1+0

Those should take you well into the next zone, Redhill Mountains.

To check on the quests you need to complete, hit T (Titles), then click on Land of Malevolence. Scroll through the right-hand window and see which quests you need to complete for the zone. If you're missing a bunch, you may need to head back to Limo Desert and fill in missing quests there.

Actually, he might be stuck with no quests because he failed to complete the chains "Envoy of the Dragon" and "Return the Glory". Those chains combine at the end of Limo to become "Magical Reconstruction" in LoM. If you are not sure if you've completed both chains, check if you've done the quest "Sacrifical Lamb" that's the last quest which combines the chains. If you've done that, Jil or another npc near her should have the quests that move you on to LoM. They will be along the wall not far from Shattered Hand Camp (I think not ingame to look at limo map).

I'm unsure whether you can get to lvl 63 *without* having done Envoy of the Dragons and Return the Glory, unless you've stoked your toon by using all of the CoO/Xaviera quests and a bunch of dailies.

If he hasn't completed those two quest lines, checking his titles (T, in game, for THH, SJF, NJF, and Limo) will show it, one way or another.
