The shine requires all the priest masks (form non-DLC ) to open, so that would mean that all priest would need to be present in the ceremony.

So, that gives more backup to the teory of the "Warlord" elected by the dragon cult, he would be given the woden mask, and all the Priest masks, we would travel to a "dimension-outside -of-the-normal-flow-of-time", he would activate the shine and be granted the Konahrik mask, and he would return later to place the mask on the same place (or someone of the cult would, if he died).

The fact that the last dragonborn can access it, well, you're murdering the priests, looting their final resting places, and sending them to Oblivion, so, i guess its fair to say that the TLD is just a grave robber, and stole the Konahrik mask.
