812.1.
Legion is a Dependent Keyword.

It is formatted as "[Legion][>] [Text]".
812.1.b.
Starting from the Keyword to the end of the clause, the entire statement is the Legion Ability.
812.1.b.1.
Legion is functionally short for “If you have played another card this turn, this card gains [Text].”
812.1.b.2.
The [Text] is the Dependent Ability.
812.1.c.
As long as a card different than the one with the Legion ability has been Finalized on the same turn then the Dependent Ability is Active on the card with Legion.
812.2.
All instances of Legion on cards a player controls are satisfied by that player playing a single card. Example: One card has three different Legion Abilities. The Legion Text of all three abilities will be active as long as one card has been played by the card's controller earlier in the same turn.
812.3.
Legion, and whether or not a card has Legion, is a characteristic of the card and may be checked or referenced by other Game Effects.

Do I get my Legion effect when I play a token or use an ability?

No, Legion will only be active if you've played a card this turn. Tokens are not cards, and abilities aren't either.

When I hide a card, does that count for Legion?

Hiding isn't playing, and doesn't count as playing a card for abilities like Legion.

Can I use Sun Disc's ability the turn I play it, counting itself for its Legion ability?

Yes. Although Legion normally requires “another" card for spells and play effects, Sun Disc's activated ability is not Sun Disc. On subsequent turns, you'll need to play another card to turn on Legion.
