Editing Tylium (TOS)

{{Disambiguation|tylium (RDM)|the fuel used in the [[Re-imagined Series]]}}

'''Tylium''' (pronounced "TIE-lee-um") is an unstable mineral element used as fuel by both the [[Colonial]] and {{TOS|Cylon}} forces in the [[Seventh Millennium]]. The substance is often mined and it can explode when energy, such as discharges from [[laser pistol]]s, impact its natural form.

Following the [[Battle of Cimtar]], {{TOS|the Fleet}} heads to the planet [[Carillon]], believing it to have tylium based on a report from an old mining expedition. Much to the surprise and shock of many, Carillon is discovered to have tylium in mass quantities, so much so that when the Colonials ignite the tylium with their energy weapons during a pitched battle with Cylon forces, the planet is [[Battle of Carillon|destroyed in a cataclysm]] {{OS|Saga of a Star World}}.

The Colonials make use of a separate fuel source, [[solium]], for fueling various ships from {{TOS|Viper}}s to freighters, like ''{{TOS|Gemini}}'' {{OS|Saga of a Star World|Fire in Space}}. This implies that tylium may well be the raw mineral from which other grades of fuel are derived, in the same way that {{w|diesel fuel|diesel}} and {{w|gasoline}} are {{w|petroleum}} derivatives.

== Tie-in Material Information ==
* ''According to [[Encyclopedia Galactica]]'' (a non-canonical piece of merchandise published in 1979):

: [[Cygnus]] was an asteroid containing an outpost of the [[Picon (TOS)|Picon]] colony, in addition to a tylium mine owned by {{TOS|Baltar}}'s family. It was captured by the [[Cylons (TOS)|Cylons]] a [[6470|century before]] the [[Battle of Cimtar]] and held for five [[yahren]] until the Colonials retook it. Baltar later turned Cygnus' tylium mine operation into the "largest intercolonial Tylium trading firm in the Galaxy". <ref>{{cite book|last=Kraus|first=Bruce|year=1979|title=[[Encyclopedia Galactica]]|pages=16}}</ref>

: The insectoid [[Ovions]] were exploited by the [[Cylons (TOS)|Cylons]] because of their mining abilities. In the course of constructing their elaborate burrows, the Ovions transported to the surface tons of nearly pure mineral ore. The Cylons established a glittering pleasure palace for humans and other beings on [[Carillon]], where food, drink, entertainment, gambling and luxury were available in vast quantities. Life was so intense that no one noticed the percentage of the "guests" harvested each day. These poor souls were killed and brought to subterranean nurseries where their bodies fed the growing larvae of the Ovion young. The Carillon pleasure palace [[Battle of Carillon|was destroyed]] by the [[Battlestar (TOS)|Battlestar]] ''[[Galactica (TOS)|Galactica]]'' in [[6570]]. <ref>{{cite book|last=Kraus|first=Bruce|year=1979|title=[[Encyclopedia Galactica]]|pages=45-46}}</ref>
