Kaledon was formed in late 1998 by guitarist Alex Mele, after he ceased activity with his former band River Of Change, together with bass player Paolo Lezziroli and rhythm guitarist Tommy Nemesio. Shortly afterwards, drummer Daniele Staccini and vocalist Alexander Penta joined the band, which started to play in a classic Heavy Metal style, influenced by Iron Maiden and Judas Priest. After a few weeks, Alexander Penta left Kaledon for conflicting schedules, being replaced by female singer Roberta Della Casa for a number of concerts in their native Rome, before settling on a full-time replacement, Anthony Drago.
In the summer of 1999, drummer Daniele Staccini was asked to leave the band, and Dario Sacco filled his place behind the kit. In the following months, Kaledon played extensively in their hometown, getting some notoriety in the Roman underground metal scene. During this time, the band decided to switch from their original sound to a German-scene influenced power metal. The guitarist Alex Mele writes a concept-story: Legend Of The Forgotten Riegn.

In this period, the keyboard player participates in the realization of two new Demo Spirit Of The Dragon II (the same preceding version, but with the keyboards) and God Says Yes I. Concluded the recordings, the band is entertained by the radio broadcast Metal Massacre, conducted by the historian figure of Baffo that is also the manager of the band.
On 16 June 2000, Kaledon played with Ronnie James Dio to the Foro Italico in Rome. Subsequently, the band replaced, for personal problems, drummer Dario Sacco with David Folchitto (drummer of Stormlord and of other band underground of Rome) and Anthony Drago with Claudio Conti.
