So if the fallen once sat under the traveller like us, so they can potentially wield light. They could potentially be like guardians. If and lets say the fallen were to switch sides and die fighting for the light. They could be reborn as a guardian. We know thats all it takes from what the speaker said before he died... Now why would the fallen switch sides? Actually it makes sense they would. Their society is tribal in nature and they stick honor bound to the law of strength. Killing or subdueing their kell rightfully makes you their leader. This is how mara sov gained dominion over the house of wolves. Until skolas lead insurrection after escaping. But we killed skolas in a trial by combat in the prison of elders fair and square. Among other kells including the house of devils. So rightfully our guardian is their new kell, should they ever choose to assert their dominion. Possibly in the form of another trial by combat. Veriks helped mara sov assert this right. If veriks were to come back, run a new challenge to bring kells to their knees. and help the guardians assert their right it could be not that long before more and more fallen houses bowed before guardians. And once again the Eliksni would walk in the light.... and who knows. Maybe in time could even ascend to be guardians of it. Maybe? Maybe I just think itd be cool to play as a hunter and be a vandal with four arms...
