The Knight of Hope could protect hope perhaps by keeping the Genesis Frog safe, as the Knight class is expected to assist the space player with the breeding duties. This would mean they’re protecting the session hope for success as without a Genesis Frog a session is doomed. The Knight could also protect a certain player who may eventually cause the session to be a success.
2) Protecting with aspect
This could mean keeping the group’s morale high and helping sad players stay cheerful, or it could mean giving the team hope somehow, perhaps by rescuing them when all seems lost. The Knight of Hope would definitely be one of the classes that come bursting in out of nowhere ready to perform a heroic rescue.
3) Using aspect as a weapon
We’ve already seen that Hope can be physically manifested to deal damage, so the Knight would likely be able to enhance their weapon with this essence of hope in order to increase their damage. You could also take this figuratively and say that they use their sway over hope to help their allies be prepared for battle.
