The Dark Heart of Sandokan is a large black crystal shard with the unique property of amplifying any energy source it is connected to, and turning the mental energy of anyone it's in contact with into telekinetic force. The Dark Heart was used by one of Sandokan's factions to power Synthos, the living weapon that eventually destroyed their world. Its malignant intelligence can use the Dark Heart's telekinetic powers to piece together new and more horrible forms for itself. Override feared that combining the Dark Heart with a Force Chip would be too much power for anyone to possess.
