If you visit your alchemy platform, can you create any potions? Even a temporary strength or dexterity potion may help escape the initial group on the fjords.
Try teleporting to the outside Sentinel Island teleporter shrine. Then you can use the dragon stone to teleport to the throne room, send your runners out for alchemy ingredients (whatever you need for the strongest healing potion you can make) and any enchantment ingredients you need (or malachite ore and diamonds to sell). Wait for them to leave the battle tower, use your dragon stone to teleport out and then back again, and they will be back (hopefully successfully). When the runners are fully upgraded (talk to your trainer and enchanter), their success rate is much improved and they bring back more ingredients at a time.
For the fjords, try just jumping off the mountain to get away from being surrounded (if you have learned Whirlwind that might come in handy to start with, or Firewall), then transform into a dragon, fly up to the top of the path, and transform back. If you start at the top you can work your way down without being surrounded (or work your way up from the bottom).
