Screenshot attached, you can see her on the right side of the staircase beside the column.
You may be having the same issue I did though. After the Campfire step, if you use the campfire at the Hovel (I think you have to currently, that step is bugged) then a duplicate Freya will spawn when you arrive. She will give you the dialogue for the next step, but there is meant to be a timegate there, so even though she tells you to go there, that step is not actually active.
You can check this in admin mode by entering QuestInfo WarriorCompanion. If the output includes the current active task as “Day4” then you are indeed at the time gate. You can either wait 8 hours (real time), or skip it using this command:
QuestRealtimeSkip WarriorCompanion:Day4
