 ##### 2.2.2.1 Players management
 `arena_lib.change_players_amount(sender, mod, arena_name, min_players, max_players)` changes the amount of players in a specific arena. It also works by specifying only one field (such as `([...] myarena, 3)` or `([...] myarena, nil, 6)`). It returns true if it succeeded.

 ##### 2.2.2.7 Music
 `arena_lib.set_bgm(sender, mod, arena_name, track, title, author, volume, pitch)` sets the background music of the arena. The audio file (`track`) must be inside the `sounds` folder of the minigame mod (NOT arena_lib's), and `.ogg` shall be omitted from the string. If `track` is nil, `arena.bgm` will be set to `nil` too
 
+##### 2.2.2.8 Celestial vault
+By default, arenas celestial vault reflects the celestial vault of the player before entering the match (meaning there are no default values inside arena_lib).  
+`arena_lib.set_celestial_vault(sender, mod, arena_name, element, params)` allows you to change parts of the vault, forcing it to players entering the arena. `element` is a string representing the part of the vault to be changed (`"sky"`, `"sun"`, `"moon"`, `"stars"`, `"clouds"`, or the explained later `"all"`), and `params` a table with the new values. This table is the same as the one used in the Minetest API `set_sky(...)`, `set_sun(...)` etc. functions, so for instance doing
+
+```lua
+	local sun_params = {
+		scale = 2.5,
+		sunrise_visible = false
+	}
+	arena_lib.set_celestial_vault(sender, mod, arena, "sun", sun_params)
+```
+will increase the size of the sun inside the arena and hide the sunrise texture. `params` can also be `nil`, and in that case will remove any custom setting previously set.  
+Last but not least, the special element `"all"` allows you to change everything, and it needs a table with the following optional parameters: `{sky={...}, sun={...}, moon={...}, stars={...}, clouds={...}}`. If `params` is nil, it'll reset the whole celestial vault.
+
+
 #### 2.2.3 Enabling an arena
 When a sign has been set, it won't work. This because an arena must be enabled manually via  
 `arena_lib.enable_arena(sender, mod, arena_name)` or by using the Enable and Leave button in the editor.
