Combining the power of creation’s First Song and the magic of the Primal Origin, Worldsingers often express abilities that join magic to music. Sometimes the power of their songs returns days after to win a battle long after they have left or fallen.
For the Worldsinger mythic path from Mythic Paths of the Lost Spheres:
Remembrance of Echoes (Mythic)
Your voice rings in the memories of your allies leading them to inspired acts long after you are gone.
Prerequisites: Echoes of Glory mythic power.
Benefit: For one day per tier, a creature you have granted morale benefits may use a move action to remember the heroism and inspiration you provided them. If they do they may renew a single morale effect you granted them within the time allowed that is then once more initiated on them for a duration of 1 round per tier. This feat can only be triggered once per creature until it is again exposed to a new morale effect by you. A creature possessing a psionic focus and at least 5 ranks in the autohypnosis skill can trigger this effect as a swift action by expending its focus instead.
