Well, in addition to being fans marvel I am also an archaeologist. Therefore I could only begin to write on the board with a discussion which I have been thinking for some time during the Special Operation. That's the meanings of the runes related to asgardian effects. All of this are in elder futhark, the most old runic alphabet. But they have various, various meanings.
Asgardian/Asgardian Emulaction: It' the rune for "A". Although it is comparable to the "a" which is the first letter for Asgardian actually the name of the rune itself, Ansuz, takes on the meaning of "God".
Call to Asgard: The rune for "H", Haglaz, it's the rune for the hail. But among the many symbolic meanings of the rune there is also that of "radical change".
Deathglow: It probably means "G". However, the name of the rune, Jeran, is clear and has the meaning of "Harvest". Pretty joke.
Deathwatch/The Eternal Vigilant: This is more complex. The name of the Algiz (or "Z") is currently a source of discussion among researchers. But probably PD took the (wrong) meaning gave at the rune by the Nazi during WWII (Life) to judge the effect of Deathwatch. Probably they took one of the "modern" symbolic meanings of the rune. For The Eternal Vigilant however is a different matter. One of the meanings historically given to the rune is "protection".
Escort of Souls: Another pretty joke, similar to Deathglow. The rune is the"R" (Raido) has the meaning of ride (... of the Valkyries) and travel.
Sacrifice: "T" (Tiwaz). The oldest meaning of the rune is "Tyr". Tyr is a Norse god who is linked to the theme of sacrifice: Fenrir, the giant infernal wolf son of Loki was menacing the gods. Tyr, brave warrior, decides to deal with it together with Odin. He sacrifices his right hand for approaching Fenrir while Odin, taking advantage of this distraction binds the beast with a magical, indestructible ribbon.
Shield-Maiden/Far Sight: "I" (Eihwaz). It means yew. But in norse mythology is associated with Yggdrasil, the World Tree. Or maybe it's a pun for "Iron"-Maiden... howerer, for Heimdall and is passive the is definitely the meaning of yew. Simply, just look at the runic poem dedicated to eihwaz rune which reads: "The yew is a tree with rough bark, hard and fast in the earth, supported by its roots, a guardian of flame and a joy upon an estate." Clear reference to the task of Heimdall of watching the Bifrost.
Sound the Alarm: "S" (Sowilo). Although the name means "sun", PD took probably once again the meaning given by the Nazi to the rune, "Victory." So, for me it's the same theory used to the meaning of Deathwatch.
For LOKI the question changes. The runes in fact at first glance does not seem to exist in the alphabet runic. This is because they are reversed as if they were reflected in a mirror! A little trick for the God of Mishief, so ...
Lie-Smith: "A". Yeah, yeah... Loki it's asgardian... but an asgardian of the Frost Giants Tribe, not an asgardian like Thor and "friends". So the "I'm-a-so-so-asgardian" explains why the rune is not in the usual position.
Trickster: "U". The name of the rune (Uruz) indicates the aurochs, that is the ancestor of the bull. It's probably a reference to the horns of this, decoration of the helmet of Loki and the horns as a symbolic element refers to demons and devils, tipice creatures devoted to the deceptions.
