Lok bo, Thu’um tu’um
[Lit. ‘Sky fly Voice down’, liberally ‘Sky above, Voice within’]
(High Hrothgar Banners)

Like kosil ‘within’, refers to something within one’s spirit or essence, something part of oneself.

Possibly derived from thu’um denoting something that lies within. May be a misspelling of tum ‘down’.

Appears in what is most likely the dragon language version of the phrase ‘Sky above, Voice within’, usually abbreviated to lok, thu’um. Unknown if a unique word or a misspelling of tum ‘down’. Appears in High Hrothgar banners spelled as ‘TuuM’. Unknown if official transliteration contains an apostrophe like thu’um or no apostrophe like gravuun.
