Can (possibly) confirm that it's not harmful.
Link leads to a game called "Shards of Eldevar". Checked out it's Weebly site and it seems mostly legit.
Don't quote me on this. Would use some antivirus scans first.
Edit: It seems that this "Shards of Eldevar" has been GMed before by Beardon himself. Most likely legit, would still scan first just to be safe.
