There's some interesting subtle information showing up in Muggleborn journal use, I think - here's my research attempting to untangle it.( Dennis's Trees )
Unfortunately, I've not been able to suss out the pattern of Dennis's use. Thoughts?( Hermione's Runes )
Hermione's rune use patterns:
" (god? ash, oak?) (2 uses): Halloween? Not the LP - other posts
mention him without this tag.
" (birch) (5 uses): Seems to be about work - the first is Hermione's introductory post in which she explains that she is an indentured worker, and the others mention her work on the Pretiosissimum Donum Dei
" (horse) (3 uses): All uses mention Crookshanks, which is interesting, since Hermione says Terry made her a tag for Crookshanks that says his name in runes. Does not occur on the most recent post, in which Crookshanks-as-Kneazle is mentioned.
" (gift) (5 uses): Does what it says on the tin. Uses are on posts about gifts to Hermione.
" (hail [precipitation]) (8 uses): Any connection I make between these posts is a real stretch. Don't know.
" (Freyr, who "bestows peace and pleasure on mortals"?) (4 uses): Protection, maybe? Used on posts where Hermione has been protected/defended (mud in Percy's bed, fighting off the troll at Halloween), wants to protect someone else (asking Madam Pomfrey not to risk getting potions supplies), or asks for protection (asking McG to see if she can ward off Carrow's creepiness).
" (ice) (3 uses): Possibly about the camps? Posts mention the camps and (in two cases) Hermione's parents.
" (year, harvest) (4 uses): Used on posts about the Pretiosissimum Donum Dei
as "harvest," perhaps?
" (torch? thorn?) (5 uses): Hurts? - some references to the Carrows and their mistreatment of Terry, one reference to Hermione's need for bruise salve and one to falling asleep in the soapsuds after a cold night in the hall.
" (man, human) (6 uses): Students, in a neutral way, maybe? Used on posts about helping students and what it would be like to be a student. Not clear if similar posts are not tagged thusly.
" (need, hardship) (1 use): Used only on the most recent post about the Carrows' destruction of Terry's clothes in the Great Hall and the cruelty of students to Muggleborns. Hermione's one real venting post, I think.
" (heritage, estate) (3 uses): Learning, probably - used on posts about learning runes, mixing potions, and learning magic secretly from Madam Pomfrey
" (mystery? chance, as associated with bad luck?) (6 uses): Terry, specifically his mistreatment?
" (ride, journey) 4 uses): Reading? Uses are on posts about books, both fixing and reading.
" (giant? thorn?) (2 uses): Used on two most recent Order Only posts where Hermione is upset with Professor(s) Carrow, but not used on an earlier post
which mentioned Madam Pomfrey's anger at Carrow's treatment of Terry, also under Order Only.
" (Tyr, who lost his right arm to the wolf Fenrir) (4 uses): Uses are on posts that mention Lupin; not used on the Halloween post
, which mentions Lupin being cross.
" (joy) (5 uses): Used on posts where Hermione is happy. :)
