History VideoGame / StarCraftIILegacyOfTheVoid

* AnAesop: Going with the game's generally bright, SpaceOpera-y feeling, Artanis' interactions with each side character tend to culminate in the mutual realization of some moral. The big themes of the game are trust, respect and unity, but individually, you get:
** Vorazun: Ethnic and cultural prejudice is silly -- every society has its strong points and weak points, and when everyone works together, everyone benefits.
** Karax: Judge a person by their deeds, not by their birth. Just because someone was raised to do one thing doesn't mean they can't grow up to be great at something different.
** Fenix/Talandar: A harsh truth is better than a gentle lie, because only with the truth can someone come to terms with it and move past it. Also: do not force your ideas of how someone would or should act on them, let them be who they want to be.
** Rohana: Upholding traditions for their own sake is blind, but disregarding tradition entirely is equally foolish. You must examine what they mean to you in the present, so you can properly decide what to carry forward and what to leave behind.
** Alarak: There are people out there whose personality and culture are just incompatible with yours. But just because you cannot be friends does not mean you must be enemies, or that temporary cooperation towards a common goal is impossible.

* MissionPackSequel: While classed as an expansion pack, and sold for $40 when it was new instead of the standard $60 of a full release, the game does not require base ''[=StarCraft 2]'' to play and adds a ''lot'' of new content (including a campaign as long as the original game's) despite using the same engine and graphics.

** In a twist of irony considering the rest of the series, [[spoiler:''all'' such conflicts are between protoss factions. Raynor's forces and Kerrigan's swarm are only too happy to work alongside Artanis. Selendis (her sane self being absent throughout the conflict) is still suspicious of Kerrigan.]] The only time this trope is ever played straight with the Zerg is during the Prologue, where Zeratul needs to rescue captured Protoss from a Moebius facility, but Kerrigan cannot wait, and felt the facility had to go because it was engineering hybrids. Said mission even gives an achievement for [[WithFriendsLikeThese killing a certain number of Zerg units.]]

** The animated backgrounds aboard the ''Spear of Adun'' gradually change the more unit types you unlock. At first there's only Zealots running around, but later you can see Stalkers [[JustForPun stalking]] the halls, High Templars running by, various ship types floating in the void outside, and even a giant Colossus stopping at the War Council for a curious peek inside before it moves on.

** The [[spoiler:Xel'naga]] were firm believers of this, [[spoiler:allowing life to achieve ascension]] at their own pace and by their own means after being seeded throughout the universe. [[spoiler:Artanis [[ExplainExplainOhCrap realizes that this revelation implies that]] the uplifting of the Protoss was ''illegal'', which meant that it had to have been a renegade Xel'naga who the Protoss worshipped.

* AdvancingWallOfDoom: An indirect one in the ''Harbinger of Oblivion'' mission [[spoiler:Where you must destroy the four void shards before the advancing wall of void energy crushes Kerrigan's swarm completely]] and a direct one in ''part 3'' of the ''Templar's return'' mission, [[spoiler:where you must get to the Psi matrix crystal and destroy it before the wall of Psi energy reaches you]].

''Legacy of the Void'' explores the racial identity of the Protoss and their fractured people -- the Nerazim, aka the Dark Templar; the rogue fanatics, the Tal'darim; the Khalai, the original caste system used by the Empire on Aiur; and the Purifiers, robotic AI recreations of deceased Protoss who had to face the challenges of WhatMeasureIsANonHuman. Artanis attempts to understand these facets of his people and what shaped them, reconcile the ideals of past, present, and future, and unite his people as one force to strike back at Amon.
