“Boats,” Nicholas Roerich, 1901, Nicholas Roerich.

“We were there!” saga began around stone-
House feasting fires. “Was but one longboat,”
Norsemen boasted, lines memorized, oft
Sang in meade-halls, ale flowing. “Ten ships
Awaited beyond distant headlands,” in unison
All offered. “Norse ships invading from
Northlands, we were witness!” Ten Vikings
Sang aloud . “Lo! One single ship made keel-
Fall upon white strands of Shetland Isles,
One amongst us explored: Shieldmaiden
Brithe, mirror of herself encountered,
Cliona, cloud-clinging Pict Druidess.”

“Who was Cliona?” Saga unfolded: Lonely
Figure, woman not of Norse clans, appeared
As mist rising from ancestral highlands,
Beachcomber like Brithe, wave-tamer,
Defender of Picts, name cliff-echoing,
“I am ‘Klee-o-na!’” Brithe’s equal as sea-
Woman, hair black as raven’s wing, clan
Gatherings respected, edge of stream sea-
Flowing they met, length of spear cast
Stood apart, like armed, dagger swift,
Arrows true, of sturdy shield, eyes sharp-
Keen upon horizon’s edge.

Two women of valor met, crossing sun-
Rising streams, suspicious and untrusting,
Chance of dagger blood-clash, suspect
Glance of eye, gleaming blades would meet.
This morn, neither would lust blood of
Foreigners, send life-spirit spiraling. With
Open hand, Brithe spoke first, “Flotnar
Systir,” tongue unknown to Cliona, sea
meaning fathomed. “Dirfiúr mara” so
Returned, two sea-sisters meeting face-
To-face on northern reaches of Shetland
Isles, explored for Norse occupation.

“The Druidess,” Odilon Redon, 1893, WikiArt.

Alliance forged upon lonely beach-head,
Brithe gave something of herself, necklace
of Christ’s cross gift recognized by Druid
Pict Cliona, pagan gods she worshiped,
Springs and wells, Iron Age rites fast-fading
In advance of monks, converts to mercurial
Christian beliefs, one god in three. Dark-
Stone amulet, Cliona to Brithe offered, end
Of Pict-kind. Cliona turned, walked away,
No footprints, disappearing into sea-cloud.
What appeared with wind, by water left,
Ghost-mirror, Brithe had befriended.

In Norse mythology, Cliona may have been a “Disir” as described in this link:
