All the Jewel's containers names are the letters of the name Thanos

T - Tesseract (Space)

H - ??? (Maybe Him, the true name of Adam Warlock, so, Soul)

A - Aether (Reality)

N - ??? (Maybe Nathanael of Kronos, in this case, is Time)

O - Orb (Power)

S - Scepter (Mind)

In some point, all of them were solid stones. So, probably, the Aether has a solid state too, as show in Svartalfheim, but currently, it is in a liquid state. Maybe the Dark Elvens transformed it in a liquid so they will can inject it in someone to create a God-like person, in this case, Malekith. This would be pretty because all the Stones are weapons. Having one of them is good but it can be stolen or lost. Having it inside someone turns impossible losing it but by absorption through magic, as we have seen
