Ailithir Longseior
At the time in which Lord Ailithir designed these arms, he was working in the Merchant Marine. The charge on the sun is an early tool of navigation.
Lord Ailithir is the creator of Scottish Rules Croquet, which he put together for the Shire of Dragon's Mist in days gone by, and which seems to slowly be gathering favor as a whimsical pastime in An Tir.
