Gana

The provided sources do not offer a single cosmogonic origin tale for the ganas as a class. Puranic narrative material cited in the sources records that, in a Shiva Purāṇa episode, Ganeśa was restored to life and thereafter appointed by Śiva as leader of the ganas (hence the titles gaṇeśa/gaṇapati, 'lord/leader of the ganas'); beyond such narrative assignments of leadership, the excerpts treat the gana primarily as an institutional/lexical category rather than advancing a unified creation myth (Shiva Purāṇa; Wikipedia).

The cited material does not provide consistent or detailed physical descriptions of individual ganas. Sources record their residence on Mount Kailash and their status as Śiva's attendants or a constituted troop; Buddhaghosa's commentary refers to 'palaces of the ganadeva-puttas,' implying a divine, palace-associated status in some traditions, but no uniform corporeal portrayal is given in the provided excerpts (Wikipedia; Buddhaghosa citation as reported in the notes).

In the available texts the gana are described and discussed primarily in social and institutional terms: as a troop or company attached to Śiva (Shiva Purāṇa; Wikipedia), as a category addressed in Vedic ritual contexts (Rigveda usage applied to the Maruts as a 'separate troop' receiving sacred praises and rites), and in the Mahābhārata (Śānti Parva, ch.108) as a subject of discussion regarding their strength, defense against disunion, subjugation of enemies, and forging of friendships. The sources emphasize organizational, attendant, and cultic functions rather than enumerating specific magical powers or abilities.
