So, I swim over to this island and as I am wading out of the water I see the back of a dragon just beyond the crest of the island. He is just sitting there next to a burial mound. The odd part is there are horkers all over this island, yet the dragon apparently doesn't care, or at least, he doesn't care until I pump an arrow into his butt.
Made for an somewhat interesting fight since I had to focus on killing the horkers first, since they were the most immediate threat, all while having a dragon breathing fire overhead.
