Memorize

Gateway and Portal are similar in that both allow rapid transportation to a
location of the channeler’s choosing. They are different in that a gateway
only works for the channeler (and, if leading a party, his or her party),
while a portal remains in place for others to use.

One can only weave a gateway or portal to a location one already knows well.
In PotP, this translates to rooms that the channeler has already memorized,
or ‘remembered’. To remember a particular place, the channeler must be
standing in that location, then ‘remember set <#>‘. Each channeler can
memorize up to ten sites (numbered 1 through 0).
