[TOMT] Fantasy cartoon that was cgi and had a character with some sort of cube

The details are very hazy but as a kid I recall watching some CGI (probably an acquired show from somewhere in Europe) where it was in a fantasy setting and the character may have had a sword but there was definitely a cube or somewhat similar shape that was important. I don't remember much, so any help would be nice. I remember catching it on Disney or Disney XD late at night but I couldn't find it on their Wikipedia pages for their former programming. There was a lot of magic and I think they were collecting something, maybe multiple cubes, not sure. Any help would be greatly appreciated.
