Follower

Followers are non-player characters (NPCs) who form an attachment to others, agreeing to follow them as friends. Followers usually receive a share of whatever treasure is gained, but they don't work for a wage; this makes them distinct from hirelings. Followers are sometimes misconstrued as retainers, who are loyal servants attracted to levelled persons who obtain name level.

Gaining Followers

Followers can be collected throughout the campaign. If the players are honest, forthright and have shown a willingness to share and sacrifice themselves for an NPC, that NPC may choose (in the DM's opinion) to become a follower. Sometimes, a character may begin the game with childhood friends as determined by the character's background, or may acquire loyal family servants who no longer require pay. Followers may be met on the road, agreeing to join forces with the players for safety's sake while travelling. Other followers might be NPCs whom the player characters rescue, or who relate to the characters and grow attached to them. A monster might be a follower; even humanoids who would normally be thought of as traditional enemies might form an association with the player characters. Followers may be steadfast for life, or they may drift in and out of the players' lives. The trustworthiness and morale of a follower towards the party depends on how he or she is treated. There's no limit on how many followers the players can have; but with too many followers, it's hard to give all of them the attention needed.

Relationships

Followers separated from the party will worry about the party's welfare. If the party is lost, they may raise a search party; if the party needs help, followers may help raise volunteers. Followers can appear in the nick of time, saving the party from a massacre. Followers may be persons of reputation and means, who can say a word on the party's behalf or proffer a loan. One-time followers may well rise to a position of authority, the benefits of which they'll share with the party they knew in those good old days, when adventure was the only thing that mattered. It's good to have friends.

A spurned follower, one who is mistreated, can become a deadly enemy. Thus one should be careful before mocking a follower's counsel or trampling upon their priorities. An ex-follower is far more dangerous than some random NPC the party once slighted. An ex-follower was invested once; and now they're hurt, misused and bitter. For those wishing to hire an assassin to kill a member of the party, they're certain to contact an ex-follower the party has betrayed.

Running Followers

Obviously, the DM shouldn't frivolously assign followers to the party, or make too much of a small rebuff on a player's part. Additionally, DMs mustn't use a follower to "run the party." The greatest intervention a follower performs is a recommended adjustment to a plan already intended by the party. Followers should offer knowledge but a minimum of insight. Followers aren't there to problem-solve for the party. They "follow." They don't lead.
