'''Basis''' is the largest [[natural satellite]] of the gas giant [[Threshold]] in the [[Soell]] system.<ref name="sybex-halo">'''[[Halo Story Bible]]''': '''Halo''', ''[[Halo: Combat Evolved: Sybex Official Strategies & Secrets]]'', ''Chapter 5'', page 63</ref> 

==Description==
[[File:H2_BurialMounds.jpg|thumb|200px|The surface of Basis.]]
Basis is the largest of the twelve satellites orbiting the gas giant [[Threshold]] in the [[Soell]] system of the [[Milky Way]] galaxy. Basis is Silvery-gray in color. [[Halo]] [[Installation 04]] was positioned in the L1 [[Lagrange point]] between Basis and Threshold.{{Ref/Reuse|universe}} Debris left over in the wake of Installation 04's [[Battle of Installation 04|destruction]] often rained down on Basis, creating small craters on the moon's surface.<ref>'''[[Halo: First Strike]]''', ''page 72''</ref>

==History==
===Forerunner era===
Circa [[97,445 BCE]], the L1 Lagrange point of Basis and its parent body, Threshold, was used by the remnants of the [[Forerunner]] [[ecumene]] as the location of Installation 04, or Alpha Halo, one of the seven ring-shaped superweapons that made up the Halo Array.{{Ref/Reuse|universe}}

===Human-Covenant War===
After Installation 04's destruction, a group of [[Covenant]] [[Sesa 'Refumee's heretic faction|defectors]] built a [[Burial Mounds|makeshift camp]] on Basis, amid the wreckage of the ring.<ref>'''Halo 2''', in-game flavor text for ''[[Burial Mounds]]''</ref> During a [[skirmish over Threshold]] following the Battle of Installation 04, [[Cortana]] maneuvered [[John-117]]'s [[GA-TL1 Longsword]] into the [[Gravity well (physics)|gravity well]] of the moon to slingshot the fighter around Basis to avoid Covenant attacks.<ref>'''Halo: First Strike''', ''page 61''</ref>

===Post-war===
After [[Human-Covenant War|the war]], [[Spartan-IV]]s were sent on reconnaissance to Basis in order to survey the debris of Alpha Halo scattered across the moon's surface. The mission marked the first use of the [[VECTOR-class Mjolnir|VECTOR-class Mjolnir armor]].<ref>'''Halo 5: Guardians''', ''[[VECTOR-class Mjolnir]] armor description''</ref>

==Trivia==
*Originally, the level ''[[alphamoon]]'' was supposed to take place on the moon Basis, after [[Sesa 'Refumee]] fled from the [[Thel 'Vadam|Arbiter (then Dervish)]] at the [[Threshold gas mine|gas mine]] over Threshold.<ref name="h3">'''[[Halo 3 Legendary Edition]]''' - ''[https://youtu.be/sBi_xx26ClM?t=1414 DVD Commentary]''</ref>
*Basis's texture in ''Halo: Combat Evolved'' appears to be a color-graded image of [[Mars]]'s surface.
*The blue coloring of Basis when seen from space is puzzling, considering that from the surface it has a hazy orange or rust-colored atmosphere and terrain. The ruddy atmospheric coloration from the ground may result from the ash and smoke thrown up by the flaming wreckage of Installation 04.
