Skyshards are listed (described) in a zone's Map Completion guide. I don't see anything that sounds like it's in the Deadlands.
Group Events are listed in the Achievements section of the Quest Journal. I see two achievements related to the Oblivion Portals, but neither is referred to as a Group Event-- although if the Ruinach Rumble isn't a Group Event, it certainly seems like the next best thing.
Blackwood has 2 public dungeons, with skyshard and groupevent/skillpoint boss. The Deadlands are something different and I think you could see them as the dolmens of Blackwood.

That is what I wanted to know. The map site shows a mark and an F5 location on it. I can now stop looking for the skyshard!
