Lost followers are not replaced. If a ranger has a limit of two followers and both are killed, he'll never receive another follower for the rest of his career.
After the DM makes the 2d6 roll to determine the number of followers, it's time to think about who or what they're going to be. He should begin by deciding the identity of the first two or three followers, so that he can make plans to smoothly introduce them into his campaign. He can determine the identities of the remaining followers later, whenever he likes.

creature he likes. Regardless of the method preferred, the DM should keep the following restrictions and recommendations in mind:
The type of followers should make sense within the context of the campaign. Lions and crocodiles shouldn't show up in the arctic, just as dolphins shouldn't appear in the desert.
The use of powerful creatures as followers should be kept to a minimum, so as not overshadow the efforts of the ranger and other player characters. It's difficult to design challenging encounters for a ranger with a dozen giants at his beck and call! Such creatures should be introduced with care and pacing; it is more fun for the player to have a chance for a powerful ally in his ranger's future.
A species enemy can't be a follower. The ranger's antagonism for his species enemy makes bonding impossible.
Generally, the follower will not be a poisonous creature. Rangers do not use poisons, and their followers tend to follow suit. Occasionally a ranger may find himself with an intelligent and poisonous follower; remember that poison use is not a good act, and that to some extent the ranger is responsible for his followers. This can be used by the DM as a special hindrance or to encourage role-playing.
Certain character kits have specific follower requirements or limitations which take precedence over other considerations. See Chapter 4 for details.
The DM may find the Follower Tables (Tables 33-43) especially useful for determining followers, as they provide a variety of types associated with specific terrains. To use the tables, select a terrain and roll 1d100. Some explanations:
If the result has an asterisk (*) and the ranger already has a follower of this type-- or if he's had a follower of that type and lost it--ignore the result and roll again.
If more than one species of a particular animal is given in parentheses, the DM can choose whichever species he likes. For example, if the result on Table 33 is a herd animal, the DM can choose either a caribou, reindeer, or musk ox.
If the result is "Human/demihuman," roll again on the Human/Demihuman Followers Table (Table 43). See the Humans and Demihumans section at the end of this chapter for further guidelines.
